To all whom v'i may conform .f

lle it known thatI we. lnitir .ili'niaain and .ix'rox t. tfltiiifigunmx, citizens ol the I 1i llnit'ed States. redding at vll'ecai'ur. in the county olidacon and State of illinois, have Device` J[or Controlling the Flow ot' Fluid. of which the following is a :rpt-cilieation.

This invention"relates to. novel in ans for controlling the flow ot' tinid, and han 'for its object to provide nieaies` for regulating the service pasagge for the lluid through a pipe or conduit and containing aloe indegendent l lor reggulating the, continuons liow of` tiuid through I aid pipe or conduit so that is to he regulated tor both service or continuous flow, or waste conditions, ellieient and' separately adjunt-V ahle iiieauf.- 'for `securingr these resulte4 are furnished. These nieand are .Shown in the present eulhodinient of the invention in connection with a stop coul; designed particularli7 for water dictrilaition; `rzhe invention. however, is not limited to .such use. hat may he utilized wherever it is desired to control the flow of fluid in connection with anyT type ot' faucet or valve.

Thisy invention is particularly valuahlc wherever a continuous low or' iiuid through a pipe in a liinited quantity is deeired in con* i'or increasing the flow lo Service proportions at will. the volume ot tiow heilig accurately regulated hy this device.

lu the tliean'inge4 l5 indicates alstop cock which may he oi any type, provided with a closing valve lo mounted on a stein l?, illustrated in the drawings; an closingl against. a seat .i8 extending aero4 and dividing the cock hotly, and ha ving` a port l!) there through for the par-rsageoi the fluid.

The-outer end of the pluiev 2t) is provided with a head l1 ha ving` `radial slots 2 ou `its peripheryinto which engages, in the preferred torni ol the invention illus` traied in Figs. l and 2. the tree lowtlr end of a locking har 3 hingtif'ed upon the sleeve 25 projecting down .troni the hotly of the cock l5. The liar has at its upper end oppositeiy disposed and laterally enti-aiding` pins `lengaging" in a recess 5 Jornied in the interior side ot the wall of the sleeve 25 whereby to hine'eifliy Support.l the han l. ttlpening into the recess fr is a slot ti extending longi tudinallvin one side oilE the sleeve 25 and in which the upper end o't the bar il freely swings.

.ln the'. Q@ is `shown another manner of ecol-ing; the har -l to the .sleeve 25. ln thin` coneiruction no recess il is inade in thc inner side of the wall of the alcove 25, hut. the enter Ieideot' the eleeve is provided with a notch il() at each side oi the slot G and spaced Slightlyr therefrom forming spaced apart luga til between 4the slot and the reapeciive notches. The har il isl hinged at its inner ind in the @lotP t3 upon a pin G2 passing through the har 3 and through the lulg til.

ln the slightly diil'erent forni shown in Fig. 2l the sleeve 25 has no internal recess 5 as in Figs. l and 2, but has an annular exterior groove '6&8 bisecting the alot. (S `and Fig. 6. Figs. 8 and 9 are views similar to which receivee a spring ring o1' pin (Si crossthe groove and passing through the inner end of the bar 3l to hingedly support" the latter 'ln the form or cocu represented 1n Fig. 1 the' sleeve 25 projects downwardly from the cock body through the center-of which sleeve the screw valve passes. rPhe exterior of the sleeve iis threaded to receive a cap or thilnhle 2G which covers the slotted head 1 of the screw valve and the bar 3, and holds the bar in engagement with the slotted head. The cap also prevents any liquid, when the device is used to control such, which may r ioastfthe screw valve, from dropping. valve 20 maybe made imperforate a `continuous flow of Huid is not del bntwhen ,in addition .a limited coniiew becomes necessary, or is def. the .'plug v-20 is perforated and threaded longitudinally for a threaded needie valve 27 provided on its outer' end with a head 7 preferably of the same diameter as the head 1 on the valve 20, and similarly slotted at 8 to engage the locking bar 3, as

shown. The inner end of the needle valve 27 is tapered as at 30 to regulate the flow or fluid through a port or by-pass 31 here shown running longitudinally through the washer screw 17a and the valve stem 17 at the center of the valve where it opens into the port 19, back along the stem for a short distance, and then opening at the sideginto the hotly. of the cock.

llhen the invention is applied to a -coclr represented in the drawings, the cap or thinible 26 is removed when adjustment is desired, and the locking bar 3 swung out trein the slotted heads of the screw/valve 20 and threaded needle valve l27, and the screw valve turned to the right or left until, with the valve 16 open, the` desired amount of iluid flows through the cock. The valve is then closed, and the needle valve 27 turned to adjust the continuous flow of fluid o the quantity desired. After the adjustnient is had the bar 3 is swung into engageient withv the slotted peripheries 2 and 8 'f the heads ol the two valves, and the cap C screwed into place. A more or less lim ited flow ot fluid will now pass continuously through the stop cock by way of the by-pass 81 through the washer screw 17a and the valve stein 17 and port 19 covered by the valve 16, escaping between the tapered end of the needle-valve 27 and the lower end of the lay-pass 31. This flow may be augmented when desired to full service volurne\ by raising the valve 16 from its seat 18, and

opening to its full extent the port' 19, the iiuid passing through said port being checked and reduced bv interference of the screw valve 20.

In the modif-led form, illustrated in Figs. 8, t and 5, the outer end of the screw valve 20 is provided with a head.21, toothed onl its periphery at 22 with which the free inwardly turned edge 2S of the leaf pawl 24E engage., said ,leaf pawl being pivotally mounted on the bottom of the sleeve 25. The needle valve 27 which is threaded into the screw valve 20, has on its outer end a head 28 preferably of the same diameter as the head 21 on the valve 20, and similarly toothed at 29 to engage the leaf pawl 2/1, as shown. Thev can or thimble '2.6 is, in a like manner as shown in Fig. 1, threaded on the sleeve and engages against the pawl 2li to hold it against the heads of the valves.

'Instead ci? using` a leaf paw'l 24 for loclring the screw valve 20 and needle valve 27, the lower end of the needle valve may be .made with a T or cross head 32 (see Figs.

5 vand 7), and on one arm thereof pivot a finger The head 21 ofI the screw valve is made in this instance with a number of radial slots 34 in its periphery, while like slots ila are formed in the lower end of the sleeve 25'. AInto these slots 34 and 35 the finger 33 is adapted to engage in the manner shown in Fig. 6, and hold both the screw valve 20 and needle valve 27 from turning. ,j

ln Figs. 8 and 9 a spring pin 36 issecured in the lower end of thesleeve 25 and projects downwardly into engagement with the serrated peripheries 37 and 38 respectively of the heads ot the screw valve 20 and needle valve 27. It is only necessary to press outwardly on the lower end of the spring pin to release the heads 21 and 28 when the valves may be turned Figs. 10 and 11 show the screw valve 20 with a polygonal outer end 39 by means of which the screw valve is turned, and a lock nut 40 on the valve 20 screwed against the hottoin oi" the sleeve 25 to prevent rotation of the screw-valve. A second lock nut 41 on the needle 'alve 27 keeps this member from turning.

Another means for holding the needle valve 27 against rotation is illustrated in 12, where a spiral or coiled spring 42 surrounds the outer end ot the needle valve and hears at its endsagainst the heads of both the screw alve and the needle valve. The spring is inade quite strong, and exerts sutlicient torce to hold the 4needle valve against rotation.

Figs. 13 and 14 illustrate another means for keeping the screw valve in position. In

4 enters to prevent it from turning. Instead of a cap or thimble on the sleeve 25, a screw 16 follows the plug in the sleeve, and forms a inish for its lower end, at the Sametime preveliting any liquid driifip'ing from the eoek which may eseape [laat the plug or Stem. n
